COTTON-GIN SPECIFICATION forming part of Letters Patent No. 766,582, dated August 2, 1904.

Application filed April 29, 1903.

To all whom it may concern.-

Be it known that I, EUGENE R. BARBER, a citizen of the United States, and a resident of Valdosta, in the county of Lowndes and State of Georgia, have invented a new and Improved Cotton-Gin, of which the following is a full, clear, and exact description.

This invention relates to a cotton-gin in which the seed-cotton is fed to a rotating drum having peculiarly-constructed teeth serving to take up the cotton and pass the same to a rapidly-rotating beater, by which the seeds are removed, after which the gin passes it to specially-arranged rocking rollers having cards thereon, the cards of one roller acting to remove the lint cotton from the drum and the cards of the other roller acting to remove the cotton from the first roller and to discharge the cotton from the machine.

This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the machine. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical section through the essential parts. Fig. 4 is an enlarged detail section taken. circumferentially of the rotating drum; and Fig. 5 is a plan view of one of the slats which are fastened to said drum and form a part thereof, Fig. 5 being on the same scale as Fig. 1.

The various parts of the gin are mounted in a suitable framing, as shown in the drawings, which framing will not be specifically described. In said framing is mounted a shaft 10, on which is fastened the rotating drum 11. Said drum is provided on its periphery with transverse slats 12, which have at their leading edges a continuous series of teeth 12, overhanging the beveled following edge 12 of the preceding slat. These slats are secured to the drum and have slight spaces between their adjacent edges, so that the cotton may be engaged securely with the teeth 1 On the shaft 10 outside the frame is fastened a sprocket-wheel 14, over wh1ch works a chain 15, this chain passing around a sprocket-wheel Serial NO- 154,817. (No model.)

16 on the drive-shaft 17, located in the forward lower portion of the machine. Said drum 11 is adapted to be turned in the direction indicated by the arrow in Fig. 3, and the cotton is fed to the under side of the drum. The feeding mechanism may be of any desired sort; but itis preferably that disclosed in my copending application for gin-feeders, filed April 29, 1903, Serial No. 15*,816. As shown in Fig. 2, the feeder comprises a conveyor 19, driven by a belt 21 and serving to carry the cotton to the conveyor 18, which is constructed to grip the cotton and carry it to the wheel 11, where it is engaged by the teeth 12" and removed from the conveyer 18. Said eonveyer 18 is driven by a belt 20. 39 indicates a drum revolubly driven by a belt 38 and mounted on a shaft 87. This drum is provided with a number of radially-movable teeth which are arranged to project beyond the drum when they move downward and to recede into the drum when they move upward. These teeth are arranged to remove the superfluous cotton from the conveyer 18 as the same carries the cotton to the wheel 11.

Fastened to the frame is a transversely-extending, vertically-disposed plate or breastbar 22, having an are-shaped lower edge 22, which is arranged to lie concentrically to the periphery of the drum 11, with its lower extremity at essentially the horizontal middle of the drum, and working in conjunction with this lower edge of the plate 22 is a horizontally-disposed rotary beater 23, this being in the form of a roller fluted. as shown in Fig. 3, and mounted on a shaft 21, held to rotate in the frame. Said shaft 21 has sprocketwheels 25 thereon, and over these wheels run chains 26, which are driven from large sprocket-wheels 27 on the shaft 17, the gearing being of such ratio as to impart a fast movement to the beater 23 relatively to the movement of the drum 11. As the seedcotton is engaged in the teeth 12 and brought up against the plate 22 the cotton is drawn under the plate, and said plate tends to press the seeds from the cotton, while the beater 23 finishes the operation by throwing the partiallyextracted seeds downward from the edge of the plate.

' continuous.

Mounted at the rear side of the drum 11 are two rolls 28 and 29, which are carried on bearing-shafts 30 and 31, these shafts being suitably mounted in the frame, and each roller being provided with cards 32, similar to those of the well-known carding-engine, the teeth of said cards being oppositely inclined, and the cards of the roller 28 being arranged to withdraw the cotton lint from the teeth 12 of the drum 11, while the cards of the roller 29 are arranged to withdraw the cotton from the cards of the roller 28. The cards 32 cover approximately half of the circumference of the rollers 28 and 29, and said rollers are given a simultaneous rocking movement as contradistinguished from a rotary movement such as that of the elements 11 and 23. It will be observed that the adjacent faces of the rollers 28 and 29 move in opposite directions. The roller 28 moves faster than the drum 11, and when said roller moves its cards rightward (referring to Fig. 3) the cotton will be gathered from the drum and held momentarily by the cards. As the cards of the roller 29 move leftward relatively to the cards of the roller 28 they will have no effect upon the cotton held in the cards of the roller 28; but as the rollers reverse their movement, the roller 28 moving its cards leftward and the roller 29 moving its cards rightward, the cards of the latter will gather the cotton from the cards of the former roller. Then upon a second reversal of the roller movements the cards of the roller 28 will return from the drum 12 full of cotton and in engaging the cards of the rightwardly-moving roller 29 will gather the cotton from said cards, and the cards of the roller 28 being full the cotton gathered from the cards of the roller 29 will be thrown upon the smooth part of the roller 29 and will necessarily drop therefrom. In this manner by the continued movements of the rollercards past each other in oppsite directions the cotton is first gathered on the cards of the roller 28, then transferred to the cards of the roller 29, and then finally ejected from the last-named roller. A certain amount of cotton will of course be carried by the cards of both rollers at all times; but after this has once accumulated the discharge of cotton will be Any desired means may be employed for imparting the above-described movement to the rolls 28 and 29. According to the construction here shown I provide each shaft 30 and 31 with a crank 33, these cranks being connected .by a link 3 and having an oscillating movement imparted thereto by a link 35, connected to a relatively short crank 36 on the rotating shaft 37 In the operation of the invention the seedcotton after being engaged by the teeth 12 of the drum 11 is carried up to the breastbar 22 and beater 23, where the seeds are removed, and then as the drum continues its revolution the rocking coacting card-rollers 28 and 29 withdraw the cotton from the drum .11 and discharge the same completely from the machine. In practice a suitable receptacle should be placed just back of the roller 29 to receive the finished product as it falls therefrom. This, however, has not been illustrated in the drawings.

Various changes-in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may said teeth serving to engage the seed-cotton,

and means coacting with the drum for separating the seeds from the cotton.
